Is radon a problem in Kelowna and the Okanagan?
Yes. The Okanagan and BC Interior are high-radon areas, with a large share of homes above Health Canada's action level (and higher rates in parts of West Kelowna and Peachland). Testing is the only way to know your home's level.
What is the radon action level?
Health Canada's action level is 200 Bq/m³. Homes above it should be mitigated, within two years, or within one year if the level is over 600 Bq/m³.
How does a radon mitigation system work?
A sub-slab depressurization system uses a sealed pipe and a quiet fan to draw radon from beneath the foundation and vent it safely above the roofline, typically cutting indoor radon by 90% or more.
Do you test radon levels too?
Yes. We provide certified testing, and if your level is above the action limit we design and install a mitigation system, then re-test to confirm the reduction.
How long does installation take?
Most homes are mitigated in a single day. We re-test afterward to confirm the system has brought levels below the Health Canada guideline.
